X terminalIn computing, an X terminal is a display/input terminal or thin client built to run an X server for the X Window System and display graphical applications whose programs normally execute on one or more remote host computers. Unlike a text-only terminal, an X terminal can show multiple applications in separate windows and accept keyboard and mouse input while communicating with several hosts over a network, typically Ethernet.
TelnetTelnet (sometimes stylized TELNET) is a client-serverapplication protocol that provides access to virtual terminals of remote systems on local area networks or the Internet. It is a protocol for bidirectional 8-bit communications. Its main goal was to connect terminal devices and terminal-oriented processes. The name "Telnet" refers to two things: a protocol specifying how two parties are to communicate and a software application that implements the protocol as a service.
Computer terminalA computer terminal is an electronic or electromechanical hardware device that can be used for entering data into, and transcribing data from, a computer or a computing system. Most early computers only had a front panel to input or display bits and had to be connected to a terminal to print or input text through a keyboard. Teleprinters were used as early-day hard-copy terminals and predated the use of a computer screen by decades.
Login sessionIn computing, a login session (or logon session on Windows NT-based systems) is the period of activity between a user logging in and logging out of a (multi-user) operating system.Login managerA login manager is a login system for Unix and Unix-like operating systems. It comprises a login daemon, a login user interface, and a system for tracking login sessions. When a user tries to log in, the login manager passes the user's credentials to an authentication system. Since an X display manager is a graphical user interface for login, some people use the terms display manager and login manager synonymously.
X Window SystemThe X Window System (X11, or simply X) is a windowing system for bitmap displays, common on Unix-like operating systems. X originated as part of Project Athena at Massachusetts Institute of Technology (MIT) in 1984. The X protocol has been at version 11 (hence "X11") since September 1987.
LoginIn computer security, logging in (or logging on, signing in, or signing on) is the process by which an individual gains access to a computer system or program by identifying and authenticating themselves. Typically, usercredentials consist of a username and a password. These credentials themselves are sometimes referred to as alogin. Modern secure systems often require a second factor, such as email or SMS confirmation for extra security.
ComputerProgrammable machine that processes dataComputers and computing devices from different eras—left to right, top to bottom: Early vacuum-tube computer (ENIAC)Mainframe computer (IBM System/360)Smartphone (LYF Water 2)Desktop computer (IBM ThinkCentre S50 with monitor)Supercomputer (IBM Summit)A computer is a machine that can be programmed to automatically carry out sequences of arithmetic or logical operations (computation).PasswordA password, sometimes called a passcode, is secret data, typically a string of characters, usually used to confirm a user's identity. Traditionally, passwords were expected to be memorized, but the large number of password-protected services that a typical individual accesses can make memorization of unique passwords for each service impractical.Getty (software)getty, short for "get teletype", is a Unix program running on a host computer that manages physical or virtual terminals (TTYs). When it detects a connection, it prompts for a username and runs the 'login' program to authenticate the user. Originally, on traditional Unix systems, getty handled connections to serial terminals (often Teletype machines) connected to a host computer. The tty part of the name stands for Teletype, but has come to mean any type of text terminal.
WorkstationA workstation is a special computer designed for technical or scientific applications. Intended primarily to be used by a single user, they are commonly connected to a local area network and run multi-useroperating systems.
User (computing)A user is a person who uses a computer or networkservice. A user typically has a user account and is recognized by the system through a username. Some software products provide services to other systems and have no direct end users. End userEnd users are the ultimate human users (also referred to as operators) of a software product. The end user stands in contrast to users who support or maintain the product such as sysops, database administrators and computer technicians.*As an Amazon Associate I earn from qualifying purchases.
